New Zealand’s Military Manual (1992) provides: “The following acts are examples of perfidy: … the feigning of protected status by the use of signs, emblems or uniforms … of neutral or other States not Parties to the conflict.”

Any person who in New Zealand or elsewhere commits, or aids or abets or procures the commission by another person of, a grave breach … of [the 1977 Additional Protocol I] is guilty of an indictable offence.
